Key Features
WLAN Standards: A device supports a number of wireless standards, that indicate the features of this device, and the standards that the wireless adapter itself must take charge.IEEE 802.11b
IEEE 802.11n
IEEE 802.11g
Other Features
802.11b Data Rates: Data rates supported by the device using this type of connection. A single device can support multiple rates données.11 Mbps, 5.5 Mbps, 2 Mbps, 1 Mbps
802.11g Data Rates: Data rates supported by the device using this type of connection. A single device can support multiple rates données.54 Mbps, 48 ​​Mbps, 36 Mbps, 24 Mbps, 28 Mbps, 12 Mbps, 9 Mbps, 6 Mbps, 5.5 Mbps, 2 Mbps, 1 Mbps
Operating Frequency: 802.11b and 802.11g standards use the 2.4 GHz signal frequency, which achieves high data rates with longer spans. The WLAN at 2.4 GHz are sometimes subject to interference from cordless phones, microwaves and other WLAN. The 802.11a standard uses for its part, the frequency of 5 GHz signal, which, besides providing a much broader spectrum, is relatively susceptible to interférences.2, 4 GHz
Modulation: There are many standards of modulation. The most commonly useds are:
DSSS
The standard DSSS (Direct-Sequence Spread Spectrum) is a transmission technology that combines the data signal to a sequence of data bits higher technique called "chipping." This ensures an increased resistance to noise and better data integrity.
OFDM
The standard OFDM (Orthogonal Frequency Division Multiplexing) is to transmit digital data by radio wave by dividing a radio signal into multiple sub-signals. These signals are then transmitted simultaneously at different frequencies. This modulation technique has the advantage of reducing the crosstalk noise.
CCK
CCK (Complementary Code Keying) uses a sequence of 64 code words 8 bits to encode data. This results in speeds of 5.5 and 11 Mb / s in the 2.4 GHz band of laOFDM
